FBI hack may raise questions about iPhone security

The FBI hack of an iPhone 5c running iOS 9 may have left the device just a little bit insecure in the eyes of some users, as the agency has not provided details of how it was able to access data on the phone used by the San Bernardino terrorist.

But the FBI did not disclose in the court filing whether it would pass the information on the hack to Apple, raising questions whether there is a vulnerability in the device that Apple may not know about.
